Abstract

The method involves producing pre-tensioning between a building and a clamping shoe (1) attached at a reinforcement laminate-end by using a hydraulic cylinder-piston unit (9) that is utilized in a device for tensioning. Pre-tensioning is maintained by driving a set-screw between a tensioning device and the clamping shoe. The piston unit is removed under retention of the pre-tensioning held by the screw. The tensioning device and the shoe are removed from a building after hardening of an adhesive. The shoe is provided for clamping of the laminate-ends and a box-type metal body (3). An independent claim is also included for a device for pre-tensioning of reinforcement laminates at a building.
